PBESERVING' VESSEL AND COVER THEREFOR.

I Patented Apr.'8,1913.

, Application filed June 3, 1910. Serial 110. 584,736.

To alt whom it may concern Be itknown that I, CHARLns A. STENIUs, a citizen of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Preserving Vessels and Covers Therefor, of which the following is aspecification.

My invention relates to the improvementof preserving vessels and covers therefor,

and the objects of my invention are to provide in connection with a jar or other receptacle, an improved constructlonof cover and sealing device, by means of which a .jar or similar receptacle may be hermetically sealed toinsure perfect preservation of the .contents of the receptacle, and to produce other improvements which willbe more fully pointed out hereinafter. These objects I accomplish in the manner illustratedin the accompanying drawing, in which Figure 1 is a view in elevation of one of my improved jars, Fig. 2 is a similar view at right angles with that shown in Fig. 1 and showing a slightly modified construction of cover, Fig. 3 is a vertical section of the upper portion of the jar indicated in Fig. 1,

\ tinuous peripheral channel or groove 3 the said section being taken on line mm of said figure, Fig. 4, is a vertical sectional view of the jar shown in Fig. 2, Fig. 5 is a sectional view on line 2 1 of Fig. 2, andFig. 6 is a plan view of the jar upon a reduced scale.

Similar numerals refer to similar parts throughout the several views.

1 represents a jar or other preserving receptacle, which may be of glass or other suitable material. In constructing the upper portion of the jar or other vessel 1, I form therein a rounded peripheral shoulder 2 and immediately above the latter, a similar although smaller shoulder or head 3, between which shoulders or beads is formed a conpurpose of which will-be pointed out hereinafter;

In constructing the cap or (cover for the vessel, I produce a cup-shaped body 4 preferably of suitable sheet metal, the upper portion of the downwardly extending side walls of said body being extended outward in the form of a projecting band, which results in the production of an internal con tinuous channel 5 and beneath this channel the wall of the cover is provided with a' continuous rounded bead-like-projection 6, be-

neath which the body'of the cover i'sfformed with av flaring terminal portion 7 Formed partly in the outwardly curved rib 6 and the terminal'member7, is a plurality of separated and vertically elongatedindentations, which result in the external projections 8.

'' On opposite sides of the base of the cover or cap, I provide downwardly extending ears p 9, which are curved to conform to the curvature of the rounded projection 2 of the jar and each of which is formed with an inturned terminal hook member 9.

Previous to the application of the above describedcover to the jar top, I fit within the inner side of the cover top and within the upper portion of the internal wall recess 5, a disk lO'of paper or other suitable ma-. terial and within said recess 5 is also fitted a yielding packing ring 11 which is formed of a suitable composition. It will be under- -stood that the outwardly and inwardly projecting rib members of the cover, are intended to closelyv embrace'the corresponding projections and recesses or grooves of the jar, thus forming a close ,fitting air tight connection of the cover and jar. When the cover is thus in its place upon the jar, it will be noted that the inner surface of the yielding packing ring 11 is in contact with the periphery of the upper portion of the jar, the outwardly projecting cover member 6 embracing'the rounded jar projection 3, and the terminal skirt or flaring member 7 embracing the upper portion of the jar projection 2. In addition to the embracing of the jar members 2 and 3 by the portions 6 and 7 of the cover, it will be observed that the inwardly projecting rib 3 which is formed be tween the members 6 and-7 of the cover, is .adapted to fit closely within the peripheral groove or recess 3 of the jar, thus more effectively sealing the cover in connection with the jar. y

- As shown in the drawing, the downwardly extending ears 9 fit over the jar projection 2. while one of the terminal hooks 9 is linked into engagement with the upper link-shaped enters and fills the recess 5 of the cover wall.

As indicated in the drawing, the inner surface of the downturned flange or wall of the glass plate 13 is formed with a continuous recess or depression 14 and into this depression is fitted a composition packing ring 16 corresponding with the ring 11. It is obvious that when the glass plate 13 is thus employed, the upper tapermg or inclined end portion of the jar whichis above itr member 3, is in contact with the inner face of the yielding packing ring 16, while the remaining portions of the cover walls embrace the projections thereof in the manner heretofore described.

It will be understood that the projections 8 which are formed as the result of indent-ations in the wall of the cover, will serve to convert the portion between said projections into spring members and aid in clamping the cover wall in proper engagement with the projections of the jar. When the internal glass plate 13 is to be employed, I preferably form the upper portion of the cover wall above the line of projections 8 with a plurality of similar projections 17 which ald in effecting a proper clamping engagement with the wallsof said glass member. y

In removing the cap or cover, it will be understood that the key 12 is detached from the hook termination of one of the ears 9, the portion of the ear forming said hook thus being sufiiciently straightened to engage the elongated opening 12 of the key. This being accomplished, the key is rotated, with the result that the ear 9 and a stri of metal forming a part of the cover and of which the ears are a continuation,- are gradually wound upon said key, with the result that a break 1s effected crosswise of the cover, which permits of the ready removal of the latter. In order to insure the tearing or breaking of the cover on predetermined lines, I preferably provide the cover top with parallel score lines which bound a diametricalstrip across said top, this strip being wound upon the key in the usual manner. In case the glass plate 13 is employed,

From the construction described, it will be seen that I have not" only provided a hermetically sealed vessel or receptacle which is particularly adapted for the preservation of meats, soups, etc., but that the sealing means are such as to prevent any contact of the contents of the vessel with the tin or other metal which comprises the cover. I

From the foregoing description, it will be seen that simple and efficient means are herein provided for accomplishing the objects of the invention, but while the elements shown and described are well adapted to serve the purposes for which they are in tended, it is to be understood that the in: vention is not limited to the precise construction set forth, but includes within its purview such changes as ma be made within the scope of the appende claim.

What I claim, is In combination with a jar having superposed external beads and an interposed channel, a cover comprising a main cup having a depending skirt I having indentations formed therein, an annular bead formed in tegrally on the skirt and adapted to embrace the uppermost bead of the jar, a flared edge partially embracing the lowermost bead of the jar, and intermediate ridge adapted to fit into the said channel, spaced legs formed integrally on said skirt and embracing the.

remainder of the said lowermost bead, and scored portions extending from said legs and merging with said cover proper whereby a weakened strip is provided in said cover. and terminating in said legs.

In testimony whereof I afiix my signature in presence of two witnesses.

CHARLES A. STENIUS.
